CCD output
Note: The CCD output must be adjusted to produce a white level at
the center and black levels near the center and 8 lines/mm
black and white pattern in other locations. Adjustment should
be made so that the center of the white level signal is delayed
528
µ
sec from the sync signal PHIT.
If this is not obtained the copy image may be shifted left or
right causing incouplete scanning.
